Carried by the portion 20 is shown a sealing means 22 as for instance of soft rubber against which the mouth of a container 23, preferably of glass, is pressed into sealing relation as by the coupling member 47 carrying the screwthreads 45.

A gasket is shown at 48 to seal the interior of the device.

5 In this form of the device the upper half of the device may be unscrewed for the removal of the container 23. In this form also the closure 49 for the container 23 carrying the sealing means 22' is secured to the closure 50 for the upper end l0 of the casing by means of the aspirating tube 5l and the vent tube 52, which latter tubes pass through the closure 50, as shown.

'I'he aspirating nozzle 53 is carried by the tube 54 sealedin the closure 50 and opening in the space between closures 49 and 50.

By virtue of use of the space 28 about the container 23 as a compressed air chamber and passages therefrom direct to the aspirating nozzle3l or 53, the usual compressed air tube from the 50 pump to the nozzle is unnecessary and the device may be of minimum diameter. The casing need be of little lgreater internal diameter than necessary to receive the container as compared with a casing large enough to contain a separate tube rom the pump to the nozzle.

Minor changes may be made in the physical embodiments of the invention within the scope of the appended claims without departing from the spirit thereof.

30 I claim:

1. An atomzer comprising, in combination: a casing; a pump piston operating in a portion of said casing to compress air therein; a liquid container; means to support the container in said casing with its interior sealed from the interior of the casing; an aspiration tube dipping into said container, passing through and sealed into an opening in a closure of said casing and formed with a nozzle projecting from the casing; an aspiration nozzle in direct communication with the space in the casing about said container and 4located to deliver a current of air in aspirating relation to the first named nozzle.

2 The combination of claim 1, with a cap 45 shaped for engagement with a nostril and enclosing said nozzles, said cap having an opening in the path of spray fromv said nozzles.

3. An atomizer comprising, in combination: a casing comprising a pump cylinder portion and 50 a liquid container housing portion in open communication the one' with the other; a pump piston reciprocable in the first named portion to compress air in the remaining portion; a closure for the housing portion; a. liquid container housed in said housing portion; a closure and sealing means for said container carried by the rst named closure; means to preserve sealing contact between the mouth of said container and said sealing means; and atomizing means carried by said first named closure comprising an aspiration tube passing throughv both closures and dipping into said container and compressed air discharge means opening through the lrst named closure into the space about said container.

4. An atomizer comprising, in combination: a cylindrical casing; a diaphragm dividing said casing into upper and lower compartments and having an opening placing said compartments in free communication; a pump piston r'eciprocable in said lower compartment; a closure for the upper compartment; a 'sealing gasket carried by the inner surface of the closure; a liquid container housed in said upper compartment with its mouth in engagement with said gasket; a spring compressed between the bottom of said container and said diaphragm to hold said container in sealing relation with said gasket; and atomizing means carried by said closure comprising an aspiration tube dipping into said container and compressed air delivery means opening into the space about said container.

5. An atomizer comprising, in combination: a cylindrical casing; a diaphragm dividing said casing into upper and lower compartments and having an opening placing said compartments in free communication; a pump piston reciprocable in said lower compartment; a closure for the upper compartment; a sealing gasket carried by the inner surface of the closure; a liquid container housed in said upper compartment with its mouth in engagement with said gasket; a, spring compressed between the bottom of said container and said diaphragm to hold said container in sealing relation with said gasket; and atomizing means carried by said closure comprising an aspiration tube dipping into container, a flaring nozzle having an opening surrounding the delivery opening of said tube and secured at its base to said closure, said closure having openings placing the interior of said nozzle in communication with said upper compartment.
